Pipe fittings are parts used to connect, control, regulate and guide the fluid in the pipeline. They are usually used in conjunction with pipelines to change the flow direction, distribute the flow, adjust the size or close the pipeline system. Pipe fittings are widely used in industry, civil and various fluid transmission systems.
Basic knowledge
Core function
Pipe fittings are an indispensable and important part of the pipeline system. Their main function is to connect, control and turn various parts of the pipeline system to ensure that the transported water, gas and other media can be safely delivered to the destination. Analogous to the vascular system in the human body, pipe fittings are similar to the joints in the blood vessels. Without joints, our entire pipeline system cannot function properly.
Common materials
The choice of material for pipe fittings has an important impact on performance and service life. Different materials are required for different scenarios and different needs. Common materials include metal materials (cast iron, stainless steel, etc.), plastic materials (PVC, PE) and fiberglass, etc.
Classification of pipe fittings
Connecting accessories
Straight-through (pipe): used to connect two pipes of the same diameter to ensure a smooth transition of the fluid. According to data from market research firm MarketsandMarkets, straight-through fittings account for 20% of the overall pipe fittings market.
Elbow: used to change the direction of the pipe, common angles are 45 degrees and 90 degrees. The use of elbows can effectively reduce the resistance to fluid flow and improve the efficiency of the system.
Branching accessories
Tee: They are T-shaped components with one inlet and two outlets at 90 degrees, used for the diversion or confluence of pipelines, usually available in two models: “male tee” and “female tee”. According to the International Pipe Fittings Association, the demand for tee fittings has increased by 15% in the past five years, mainly due to the rapid development of the construction and oil industries.
Closure accessories
Valves: Used to control the flow of fluids, including gate valves, ball valves and butterfly valves. The valve market is expected to reach US$10 billion in 2025, with a compound annual growth rate of 5.6%.
Plugs: Used to close the end of the pipeline to prevent fluid leakage.
Support and counterweight accessories
Brackets and hangers: Used to fix the pipeline to ensure its stability and safety during use
Functions of pipeline accessories
Connection function: Connect two or more sections of pipeline.
Directional change: Change the direction of fluid flow, such as elbows.
Size adjustment: Connect pipes of different diameters or thicknesses, such as reducers.
Switch control: Used to manage the flow of media in pipelines through accessories such as valves.
Add branches: Use components such as tees or crosses to achieve pipeline diversion.
